LAST.

SPECIFICATION forming part of Letters Patent N 0. 673,131, dated April 30, 1901.

Application filed March 30, 1900. Serial No. 10,800. (No model.)

To ctZZ whom it may concern:

Be it known that I, MATTHIAS Bnooiga citizen of the United States, residing at Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Lasts; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The present invention relates to lasts, and more particularly to that type of last which is formed of two parts united by a hinge and generally known as hinged or divided lasts.

In the use of hinged lasts in making some types of shoes, such as McKay sewed shoes, the lasts are provided along the bottom with a metallic clenching-plate for the purpose of turning over and clenching the points of tacks driven in the insole.

It has been found that quite frequently a tack or nail instead of striking the clenchingplate will enter the space between the meeting ends of the plate-sections and be projected into the space between the sections of the last. The tack therefore will not only fail to be clenched, thus necessitating the subsequent removal of its projecting point, but it renders difficult the removal of the last from the shoe, often causing a distortion and damage to the sole and upper and being in other ways a source of annoyance and difficulty, as is well known by those skilled in the art.

The object of the present invention is to provide a hinged or divided last with a clenching-plate which will prevent the entrance of a tack between the sections of the last and insure the proper clenching thereof, thus obviating the difliculties above noted.

To the above end the present invention consists of the improved last, which will be hereinafter described and claimed.

The present invention is illustrated in the accompanying drawings, in which Figure 1 shows a last embodying the same and partially broken out to illustrate the invention. Fig. 2 shows a bottom plan view of the last.

Similar letters of reference will be employed to designate corresponding parts.

The-last,as shown,comprises afore-part section a and a heel-section b, which in the illustrated embodiment are united by a hinge 0, whereby the heel-section may be turned up, as shown in dotted lines, Fig. 1, for the purpose of shortening the last when inserting or removing it. A sliding bolt d, fitted in a recess e and acted on by a spring f, bears against the heel-section and assists in maintaining the last in operative position,as shown in full lines, Fig. 1.

The last as so far described is one well known in the trade and in and of itself forms no part of the present invention.

Thelast is provided with a metallic clenching-plate, which, as shown, is formed in two sections to permit the relative movement of the sections of the last as described-a section g, conforming to the outlines of the bottom of the fore-part section CL, and a section h, conforming to the outlines of the bottom of the heel-section b, the sections 9 and It being secured to the respective sections of the last by screws 7; or by any other suitable means.

In order to prevent the entrance of a tack between the sections of the clenching-plate and last, one of the sections of the clenchingplate is provided with an extended orprojecting edge k, which is designed to overlap'the adjacent edge of the other section. This overlapping edge may be formed on either section of the clenching-plate; but it is preferred to form it on the section It, attached to the heelsection of the last, as shown in the illustrated embodiment.

In order to produce a smooth joint, the meeting faces of the sections 9 and h are preferably beveled, as shown at m.

It will be readily observed that when the last is in the shoe the projecting edge 7c of the section 77. of the clenching-plate will overlap the meeting edge of the section g and efiectually prevent the entrance of a tack between the sections of the last, insuring the clenching of all the tacks driven through the insole.

plate secured to the bottom of the heel-section of a divided last and overlapping the fore-part Having described my invention, I claim as new and desire to protect by Letters Patent of the United States i A divided last provided with a divided clenching-plate, the sections of the clenching-plate overlapping each other and having their overlapping portions beveled, substan tially as described.

In testimony whereof I affix my signature in presence 'of two Witnesses.

MATTHIAS BROOK.
